Six Flags St. Louis · US & Canada · typical hours 10 AM–9 PM
The one-minute version: be at the gate 30–45 minutes before opening and ride American Thunder first. Waits peak from late morning to mid-afternoon — do shows and meals then. The final hour is often as quiet as rope drop. There is no headline evening show, so the final operating hour is usually the quietest time to ride.
Usually not worth it: One of the quieter Six Flags parks.
